settopbox no screen

quite new to this forum, please advise where i have to look.
- i have connected the vidon.me set-top box to my sony bravia via hdmi (port 7)
- sony does not support 1080p
- when starting up i see the vidon.me logo, resolution 720
- next i see the logo again, resolution 1080i
- next the screen disappears to 'dots and dashes' and no way to see where you are
- sometimes the screen flashes but it is al gibberish
- could be the ntsc/pal problem, but i have no ntsc capable device to check

installed vidon.me remote on ipad - chinese interface + no option to configure
however the vidon.me is there and configured via dhcp
address of the vidon.me is 192.168.1.130 on my local lan, browsing gives 'file not found'

so i am stuck: can't configure via ip and can't configure using the telly (also used another hdmi port, same problem)
any ideas?
